Add log messages to the certificate callback path.
Logs are meant to test 2 theories regarding the
SIGSEGV in the attached bug:
1. Failure is happening somewhere in the middle
of the call path from tls_openssl to AIDL.
2. sm struct becomes stale before the callback is
used.
Bug: 275293332
Test: Connect to WPA-Enterprise network and verify logs.
